ET4035 - 50Amp Circuit Breaker

ET4035 - 50Amp Circuit Breaker

When you need a replacement breaker that matches the original equipment, the ET4035 offers the ratings and configuration needed for many 480VAC distribution systems. This 50 Amp, 3-pole Type F molded-case circuit breaker is designed for applications requiring a 14 kA interrupting capacity at 480 VAC and operation in ambient temperatures up to 40°C.

Whether you're replacing a failed breaker during routine maintenance or servicing existing electrical equipment, matching the original specifications is essential. The ET4035 is intended as a form, fit, and functional replacement for compatible installations, allowing existing systems to remain configured as designed.
